Product Description

Stainless steel square tubes are hollow, square-sectioned steel strips, hence the name. These versatile tubes are extensively employed in the transportation of fluids such as oil, natural gas, water, gas, and steam. Notably, their unique blend of bending and torsional strength combined with a lightweight structure makes them indispensable in the creation of mechanical parts and engineering structures.
Stainless steel square pipes come in two primary categories: seamless steel pipes and welded steel pipes. These can be further classified by their cross-sectional shapes into square and rectangular pipes. While round steel pipes are the most prevalent, there are also semicircular, hexagonal, equilateral triangle, octagonal, and other specialized shapes available to meet various needs.
To ensure the integrity of stainless steel square pipes under fluid pressure, rigorous hydraulic tests are performed. These tests confirm the pipe's ability to withstand pressure without leaking, wetting, or expanding within the specified limits. Additionally, certain pipes may undergo crimping, flaring, and flattening tests to meet specific standards or customer requirements.
Square tube specification: 5*5~150*150mm Thickness: 0.4~6.0mm
Square pipe material: 304, 304L, TP304, TP316L, 316, 316L, 316Ti, 321, 347H, 310S
